LPF Exam 3 Review | UPDATED What do fungi and arthropods have in common - both groups have chitin Specialized symbiotic associations between the roots of plants and fungi are called - mycorrhizae A mass of hyphae is commonly referred to as - a mycelium A symbiotic association between fungus and a green alga or a cyanobacterium is called a - lichen Which of the following refers to a symbiotic relationships that involve fungi living between the cells in plants (several synthesize alkaloids) - endophytes What is the process called in which two haploid fungi nuclei fuse to forma diploid nucleus - karyogamy Which of the following is MOST CORRECT regarding fungal phylogeny - fungi are more closely related to single celled protists, called nucleariids than animals Most animals undergo which of the following patterns of embryonic development - zygote morula blastula gastrula What do animals as diverse as corals and monkeys have in common - presence of Hox gene At which developmental stage should one be able to first distinguish a diploblastic embryo from a triploblastic embryo - gastrulation Jaws first occurring in which extant group of fishes - chondrichthyans Ediacarans - were around during the Neoproterozoic (1bil-542mya), were soft bodied multicellular organisms, declined during the Cambrian explosion and were among the first animals An adult animal that possesses bilateral symmetry is most certainly also - triploblastic Which of the following characteristics generally applies to protostome development - determinate development Rotifers are microscopic animals with true tissues and organ systems. Some of the unique characteristics of rotifers include - a corona used to create a water current for feeding AND a mastax in the pharynx for crushing food What is the point of conflict between the cladogram hypothesis presented in the two figures - the relationship of ectoprocts and brachiopods to other phyla The presence of a coelom is used as a clade to group animals - false Sea sluds can obtain nematocysts by preying on - cnidarians such as anemones Gastropods, including sea slugs, are most closely related to (in the same phylum as) which group of animals - cephalopods Several animal species are parthenogenic, including a group of rotifers. What does this term mean - asexual reproduction where females are produced from unfertilized eggs Sponges in the phylum porifera - have no true tissues Two phyla which belong to the Ecdysozoan clade are - nematode and arthropoda Sponges are unique in possessing special flagellated cells whose beating drives water through the body cavity. These specialized cells are known as - choanocytes The long flat bodies of tapeworms are made up of repeating segments known as - proglottids All of the following statements about Cnidaria are correct with the exception of - cnidarians are triploblastic, having ectoderm, mesoderm and endoderm Many marine molluscs have a distinct larval phase called - trochophores Members of the phylum annelida are - segmented and belong to the clade
